World’s Fastest Commodore PET using the MCL65+ 6502 drop-in emulator

I recently acquired and restored a Commodore PET 4016, so I thought it might be fun to try replacing the CPU with an MCL65+ 6502 drop-in replacement board to see how it performs. I also was interested to see how much faster the PET can operate when running in some acceleration modes! My PET 4016, [ ]
